Agree with tParse. Unless I can find an inexpensive source for "purified" or distilled water, I'd likely avoid. And, ( I looked up the brand ) I saw that this model uses 280W of electricity. Until I get a few solar panels ;-) that's a bit much for me to run. I think I'm going to look into the semi-passive systems (like AprilAire) that attach to my furnace. Thx for sharing, regardless. Made me think/look, as I'm struggling keeping % above 35.
